By checking the "Enable reassignment" box in Izotope RX while using time&frequency overlaps, you can get fine pitch tracking like in the first image below from a singing female voice ("shafqat.aif" cnmat audio example), far better than standard FFT without overlap (2nd image).

The wavelet window software didn’t really convinced me about wavelets finally, plus it is damned slow. I find FFT with reassignment and overlaps more precise than wavelets.

(By the way, RavenPro also have time and frequency overlaps option, but it is lost behind hundreds of option, i just found it in "configure spectrogram".)
